Ezgo rxv golf cart

I also have a ezgo rxv besides my gem, I’m having an issue with the rxv that is not moving at all is a 2017 model I have replace the solenoid, charging receptacle, and the tow and run switch but still no movement or sound when switched to reverse or forward. Any idea where I should be looking at?
Thank You
Dave.

Buy a service manual and use the trouble shooting tree.
